REVERSIBLE BROILER.

SPECIFICATION forming part Of Letters Patent N0. 244,060, dated July 12, 1881.

a Application filed March '7, 1881. (No model.)

I all whom it may concern:

Be it known that we, WILLIAM J. JOHNSON, residing at Newton, Massachusetts, and J 0- NAH H. BIGELOW, residing at Worcester, Massachusetts, have jointly invented certain new and useful Improvements in Reversible Broilers; and we do hereby declare that the same are fully described in the following specification and illustrated in the accompanying 1o drawings.

This invention is in the nature of an improvement on the broilin g apparatus described in the Letters Patent granted to us February 1, 1881.

I 5 The present improvement consists in a reversible broiler having its wings united for folding by means of joints so constructed and arranged as to give a'wider space between the entire wings when folded in one direction than when reversed, and provided with a locking device to unite the handles in either position.

This invention also consists in a reversible broiler having its wings loosely united, so as to give a greater space between them when folded in one direction than when reversed, and provided with projecting handles, one of which is offset or thrown out of line, as shown, so that with a locking-slide adapted to engage the handles when folded either way, the

wings will in either case be held parallel to each other.

The present improvements are fully embodied in a broiler characterized by both these peculiarities.

3 5 Our former patent explained that reversible broilers with locking-slides were old, but that by reversing no advantage was gained, since no variation in space followed; also, that broilers having varying spaces between the wings when in the two positions had been longknown, but without a lockin g device for both positions. We then described certain devices whereby the desired variation was attained and the parts locked in either position. In such devices the bars of each wing were shown so located or bent as to be nearer together or farther apart in the respective positions, but the outer end frames were at a uniform distance in either case, since the links uniting them were unvarying.

The first of our present improvements varies the distance of the end frames as well as the parallel bars in reversing, the joints being so constructed as to allow the entire wings to approach or separate. The advantage of this feature will be apparent in cases where the articlebeingbroiled or toasted projects between or beyond the end frames, the capacity of the utensil being evidently thereby increased.

The second of our present improvements 6'0 maintains true parallelism, or gives four adjustments to the wings, as will be explained.

In the accompanying drawings, Figure 1 is a side view of a riveted broiler embodying both features of our invention, the reverse position being shown in dotted lines. Fig. 2 is an enlarged perspective detail of another form of broiler, with a different arrangement of the hinges and links; Fig. 3, a modification, in which the loose connecting links are dispensed with; and Fig. 4 a detail showing the bandles united by a double-looped slide.

A B are the straight parallel bars of the wings, joined, respectively, to the end frames,

C D. These end frames approach or separate 7 5 in folding by reason of the construction or arrangement of the joints.

In Fig. l the joints are formed by extending, at each side of each wing, two of the gratebars beyond the end frame, deflecting these extended parts E E toward each other, and uniting them by links F F, so as to leave the wings quite widely separated; but by reversing, as in the dotted lines, the deflection of the parts E E is outward or from each other, and the wings are brought closely together. Any desired variation can thus be effected in a very simple manner, and its extent readily changed by increasing or reducing the deflection. In Fig. 2 the same result is attained by c extending vertically a single wire only from each side of each wing, as shown, and forming its end into an eye, E, to receive the ring or link F. Similar joints have before been made, except the deflection of the parts E E in Fig. 9 5 1that is, with the extensions made straight.

Eyes like those in Fig. 2 have also been used, extending from each wing horizontally outward, and connected by rings. In neither case was there any variation in space attained in reversing the wings.

In Fig. 3 the loose links F are dispensed with, the upper wing having rigid horizontal eyes G, formed by extensions of its marginal bars, and the lower ring having such extensions formed into rigid vertical loops H, passing downwardly through the eyes Gr. Said loops extend but a short distance below the lower wing, so that when reversed the wings are held in close proximity, as indicated in dotted lines. These devices serve to vary the distance of the wings by adjustment at the hinged end of the utensil. Our improvements also contemplate a corresponding adjustment at the handle end, which we accomplish, by preference, in the manner indicated in Fig. 1.

The handles I J are, as usual, continuations of central bars of the two wings, the longer handle having the locking-slide K secured movably upon it, so as to slip on and off the shorter one. Instead of extending both handles straight out, as heretofore, we form an offset or shoulder, I, on one of them, about as shown, so that when the slide is on the outer end of the handle I, beyond the offset I, the end frames adjoining the handles will be farther apart in one folded position than in the other, corresponding to the variations eifected at the other end by the jointing. In this manner the bars A and B of the two wings will lie parallel to each other in either folded position. This result may also be accomplished in broilers having our several improvements for varying the distance in reversing the wings by employing a double slide, K, having a deep and a shallow loop, with eyes or guides for the passage of the wires of the longer handle. Double slides having two equal loops are shown in the Patent of Dudley, dated April 6, 1875, which has no variation in space at either end by reversing.

By making the offset shown in Fig. 1 in the middle of one of the handles and employing the locking-slide four variations in distance of the adjacent end frames can be made, two of them due to the slide being applied upon the outer end of the handles, beyond the offset I in each of the folded positions, and two arising from locating the slide between the offset I and the end frame and reversing the wings. These changes give a wide range of adaptation, together with intermediate adj ustments.

We claim as of our invention- 1. A reversible broiler having its wings united for folding by means of joints, constructed and arranged as described, to give a wider space between the end frames of the wings when folded in one direction than when reversed, and provided with a locking device for securing the handles when folded either way, for the purpose set forth.

2. A reversible broiler consisting of two folding wings united by offset-joints outside of the cross-bars O, as deseribed,whereby the entire wings are farther apart in one position than when reversed, and provided with proj cctin g handles, one of which is offset, as shown, and a lockin g device adapted to engage both handles when folded either way, for the purpose set forth.

3. Av reversible broiler having two folding wings united by offset-joints, as described, and provided with projecting handles, and a locking-slide formed with a deep and a shallow loop to engage the short handle when folded either way, whereby the distance between the wings is increased or diminished by reversing them, and they are held parallel to each other, substantially as set forth.

In testimony whereof we hereto afiix our signatures in presence of two witnesses.
